Abstract
The utility model discloses a bed sediment digging shovel, which comprises a shovel handle, a shovel loader and a dragger, wherein the shovel loader is fixed at the lower end of the shovel handle. The bed sediment digging shovel is characterized in that the shovel loader is formed by connecting three triangular surfaces two by two, and a tetrahedron of which one surface is opened is formed; and the dragger has the same shape as that of the shovel loader and is arranged in the shovel loader. According to the technical scheme, the bed sediment digging shovel can quickly dig out bed sediments without losing nutrients in the bed sediments.
Description
Technical field
The utility model belongs to technical field of tools, is specifically related to a kind of riverbed bed mud sample digger blade.
Background technology
When carrying out some experiment, to the bed mud on the riverbed be detected, therefore need dig out the bed mud sample.The excavation of bed mud seems simply, but in fact is faced with the following problem: in some hard bank slopes, the top of bed mud often covered one deck mud, so difficult to dig out; And in transporting the process of bed mud, current are also taken away the bed mud that digs easily, or are to make wherein a large amount of microorganism forfeitures, make experimental data inaccurate.
Mostly present instrument is article such as scoop, or directly digs out with hand, but river has fluctuation, and human at the incoming tide being difficult to dug out bed mud by means of the height of self, and scoop often is difficult to keep the former state of bed mud, and damages plant easily.
Therefore be necessary to design one and can dig out bed mud to greatest extent, preserve the instrument of the microorganism that wherein awaits detecting, nutriment, polluter etc.
The utility model content
To above-mentioned problem described in the prior, it is simple that the utility model proposes a kind of making, easy to use, can excavate the riverbed bed mud rapidly and not cause the wherein instrument of nutriment loss.
To achieve these goals, the technical scheme of the utility model is following:
A kind of riverbed bed mud digger blade comprises spade, scraper bowl and drags for son that scraper bowl is fixed on the lower end of spade; It is characterized in that said scraper bowl is formed by connecting three gores in twos, form the tetrahedroid of an opening; The said son that drags for has the shape identical with scraper bowl, is arranged in the scraper bowl.
The said son that drags for has handle, and handle is provided with some screws or pin-and-hole, said spade be provided with the handle that drags for son on identical screw or the pin-and-hole of screw size, drag for the insert-pull pin assembly connection that son is connected through screw and nut with spade or is convenient to dismantle, installs.
Said spade upper end can be provided with one group up and down two pin-and-holes or screw be used for the spreading spade, the long joining section two ends that are used for the spreading spade are equipped with corresponding one group of two pin-and-holes or screw up and down.Spade does not need spreading when the depth of water is more shallow, when the depth of water is dark, can pass through insert-pull pin or screw and nut with the spade spreading.
Scraper bowl is alloy steel, steel disc, iron plate or aluminium with the material that drags for son, and according to the different thickness differences of getting of the strength of materials, thickness is 1～3mm.
The length of spade is 1～3m.
The height of scraper bowl is 60～100mm.
Through such design, when excavating bed mud,, conveniently go deep into inside, riverbed because it has sharp-pointed and little head, can not take mud out of, because volume is little, can not take plant roots out of simultaneously; Again because this instrument has scraper bowl, place a hopper of being convenient to topple over bed mud in the scraper bowl and drag for son, can smoothly bed mud be retained and be poured onto easily in the sampling jar, prevent the loss of microorganism simultaneously; Simultaneously,, be convenient to the application of force, also can not stir bed mud simultaneously because it has long spade.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the utility model.
Embodiment
Below in conjunction with specific embodiment, further set forth the utility model.
As shown in Figure 1, the riverbed bed mud digger blade of the utility model comprises spade 1, scraper bowl 2 and drags for son 3; Spade 1 is collapsible, and scraper bowl 2 is fixed on an end of spade 1, and scraper bowl 2 is formed by connecting gore 201, gore 202 and gore 203; Form the tetrahedroid of an opening; Drag for son 3 and be formed by connecting in twos, have the shape identical, be arranged in the scraper bowl 2 with scraper bowl 2 gore 301, gore 302 and gore 303.
Dragging for son 3 has handle 304, and handle is provided with screw, spade 1 be provided with the handle that drags for son on the identical screw of screw size, drag for son and be connected with nut 101 through screw 305, or adopt pin configuration easy to plug with spade.
Scraper bowl in the present embodiment with drag for son and adopt steel disc to process, thickness is 1～3mm; The length of spade is 2m; The height of scraper bowl is 50mm～100mm.The length of spade is through pin or screw assembly scalable.
During use, scraper bowl is firmly inserted in the riverbed bed mud, drag for son and be brought in the bed mud simultaneously.To drag for son and take off and extract, bed mud is taken out of the water surface smoothly, pours sampling jar into and accomplishes sampling.
The foregoing description be interpreted as only being used to the utility model is described and be not used in the restriction the utility model protection domain.After the content of having read the utility model record, those skilled in the art can do various changes or modification to the utility model, and these equivalences change and modification falls into the utility model claim institute restricted portion equally.
